php - Create a Insert... Select statement in Laravel

Question

I'm needing to convert this query for Laravel and I'm having issues trying to create an Insert... Select statement using Laravel's Eloquont ORM, or Queries. I'm not sure how I would go about creating this query.

Insert into Demand (Login, Name, ApptTime, Phone, Physician, Location, FormatName, FormatDate, FormatTime, ApptDate, FormatPhone, cellphone)
Select Login, Name, ApptTime, Phone, Physician, Location, FormatName, FormatDate, FormatTime, ApptDate, FormatPhone, cellphone from " . [dbname] . "
    Where " . $where_statement

How is it possible to create this query using Laravel's ORM?

EDIT: I'm not sure if this is clear, but I'm thinking in terms of 1 query, like they do here http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

There is no way of doing this in one query (unless you are on Laravel 5.7), however I came across the same issue and wanted to make sure I can keep using a certain select I build with the QueryBuilder.

So what you could do, to keep things half what clean and to reuse functionality which has built a select statement before, is this:

/**
 * Wherever your Select may come from
 **/
$select = User::where(...)
                  ->where(...)
                  ->whereIn(...)
                  ->select(array('email','moneyOwing'));
/**
 * get the binding parameters
 **/ 
$bindings = $select->getBindings();
/**
 * now go down to the "Network Layer"
 * and do a hard coded select, Laravel is a little
 * stupid here
 */
 $insertQuery = 'INSERT into user_debt_collection (email,dinero) '
                . $select->toSql();

 DB::insert($insertQuery, $bindings);

UPDATE Laravel 5.7

As of Laravel 5.7.17 you can use ->insertUsing(). See here for details. Thank you @Soulriser for pointing this out.

So above query would look like this:

DB::table('user_debt_collection')->insertUsing(['email','dinero'], $select);
